It's official!

Zayn Malik posted his first Instagram with girlfriend Gigi Hadid, on Sunday, and boy are fans eating it up and cursing the couple with equal zeal!

The former One Direction singer, 22, is seen cuddling the 20-year-old supermodel. Gigi's squeezing her man's face and puckering for the camera.

Fans' comments ranged from "OMG, I love them so much my heart hurts." to "She went from Cody to Joe to Zayn in a hot minute!" to the occasional, simple "Daaamn."

Gigi and Zayn first started dating a month ago as they made appearances together at LA nightclubs, hand-in-hand. Since then, the couple has kept their relationship fairly private, so this social media posting marks a significant step in their relationship ... right?
